3. Screw in the special tool until it comes in contact 

with the timing belt tensioner arm.

CAUTION

The special tool can be gradually installed at a 
rate of a 30 degree turn per second. If it is 
screwed in all at once, the timing belt tensioner 
adjuster rod will not easily retract and the special 
tool may bend.

CAUTION

For reinstallation of the valve timing belt, draw an 
arrow indicating the rotating direction (clock-
wise) on the back of the belt using chalk.
6. After removal of the special tool, loosen the timing 

belt tensioner pulley mounting bolt and remove 
the valve timing belt.

NOTE: Secure the removed power steering oil pump 
assembly with cord or rope at a position where they 
will not interfere with the removal of the balancer tim-
ing belt.

timing marks are aligned.

2. Install the balancer timing belt on the crankshaft 

balancershaft drive sprocket and balancershaft 
sprocket. There should be no slack on the tension 
side.

3. Assemble and temporarily fix the centre of the 

pulley of the balancer timing belt tensioner so that 
it is at the top left from the centre of the 
assembling bolt, and the pulley flange is at the 
front-side of the engine.

4. Adjust the balancer timing belt tension.

TENSION ADJUSTMENT 

CAUTION

When tightening the mounting bolts, ensure that 
the tensioner does not rotate with the bolts. 
Allowing it to rotate with the bolts can cause 
excessive tension of the belt.

AC102691AB

Belt tension side

1. With your fingers, lift the balancer timing belt 

tensioner in the direction of the arrow. Apply 
pressure of 3.0 

± 0.4 N⋅m to the balancer timing 

belt. Tighten the assembling bolt to the standard 
torque. Then, fix the balancer timing belt 
tensioner.

Tightening torque: 19
